@article { , title = {Reversibility of the Mullins effect for extending the life of rubber components}, abstract = {This paper investigates the recovery of the Mullins effect by heat-treatment of predeformed (300\% tensile strain) carbon-black filled ethylene-propylene-diene rubber (EPDM) in an air-circulating oven. The tensile response was measured, and the secant modulus at 100\% strain, energy to deform to 300\% strain, ultimate tensile strength, strain to failure and permanent deformation were compared to undeformed specimens subjected to the same heat-treatments, 3–24 h at temperatures of 60–80°C. Recovery of properties is dependent on time and temperature of treatment, increasing with longer times and higher temperatures. Recovery of secant modulus follows time-temperature superposition (TTS) with an activation enthalpy of 111 kJ mol−1; TTS is shown to be applicable to the other measures, probably because of additional cure in the rubber resulting from the heat-treatment. Treatments under vacuum led to similar effects as in an air-circulating oven.}, doi = {10.1080/14658011.2018.1443384}, eissn = {1743-2898}, issn = {1465-8011}, issue = {1}, journal = {Plastics, Rubber and Composites}, note = {12 mo. embargo.
